I post the review from section 8 until the end. Fragmentation - "If the datagram does not fit within a single L2 data unit, it SHALL be broken into fragments." And if not broken into fragments, the alternative is to drop the packet? - "Things (End Systems)" There was recently a discussion on using or not the term "Things" for devices. This shall follow the results of this discussion. - "topology, and therefore" remove comma. Reliability options: discussion - "Figure Figure 7 summarizes" remove one "Figure" - "provides flow control" I don't know if this is exactly flow control in the terms of what it is known in TCP. For TCP, one lost packet signals that the bandwidth limit for the flow is full (probably due to congestion), and there is no congestion at the lpwan level. What is true is that this mechanism stops - Figure 7 Do we differentiate Figures and Tables? Fragmentation header formats I am worried about the "SHALL" term. The header MUST be as described, if not, there will be no interoperability. I suggest to describe the fields of the fragmentation header before the types of header. One has to wait to the last one to understand them. I can understand you have to create a rule for each fragmentation reliability option used. Am I right? - "options, N equal to or " remove CR/LF -"The ACK provides" remove CR/LF -"sender renumbers the CFNs remove CR/LF Aborting a fragmented IPv6 datagram transmission *As it is defined in this section by *TBD_ABORT_RX*, it would be practical to have a list * *of rule identifiers required to implement fragmentation.* *- "* on- going," remove space. Security considerations for fragmentation - "{HHWH}" what is this? -- DIEGO DUJOVNE Profesor Asociado Escuela de Informática y Telecomunicaciones Facultad de Ingeniería - Universidad Diego Portales - Chile www.ingenieria.udp.cl (56 2) 676 8125
